I am wanting to put a "better" rearend in my factory original 69 Mach 1. Ratio is high - 3.0, I think - so I am wanting something like 3.50 or 3.70 with posi. Car will be used for occasional cruising, not raced, but I want it "snappy".
First, I don't know if it has the 28 or 31 spline axles. Also, should I buy a complete 3rd member and swap out the old one or buy the necessary parts to build it from scratch?
Either way, I would also want advice on which brands or companies to go with. I see a lot of stuff offered on Ebay, but don't want to go the wrong way.
I am also about to have the engine built. I will go with a fairly stock setup - only adding a cam, carb, intake combination to increase stock hp to something around 320-340 hp (that's another post for another day!).
